do you know anyone in the area that can show your property for you? If you don’t then maybe you could advertise for a pensioner to do this at a small renumeration for there trouble.
Good Luck I know what you are experiencing when it comes to managing your property from a distance, it is not easy but it is not impossible. Hang in there you will find an answer that will suit you I am sure.
